discrimination of wild and cultured european sea bass (dicentrarchus labrax) using chemical and isotopic analyses.recent legislation in the european union (ec/2065/2001) requires that seafood must provide the consumer with information that describes geographical origin and production method. the present studies aimed to establish methods, based on chemical and stable isotopic analysis, that could reliably differentiate between wild and farmed european sea bass (dicentrarchus labrax). the study measured fatty acid and isotopic compositions (delta13c and delta18o) of total flesh oil, delta15n of the glycerol/ ...200717595104
high site fidelity and low site connectivity in temperate salt marsh fish populations: a stable isotope and juvenile fish utilise salt marshes for food and shelter at high tide, moving into adjacent sublittoral regions during low tide. understanding whether there are high levels of site fidelity for different species of coastal fish has important implications for habitat conservation and the design of marine protected areas. we hypothesised that common salt marsh fish species would demonstrate a high site fidelity, resulting in minimal inter-marsh connectivity. carbon ((13)c) and nitrogen (( ...201121786154
